Abstract

Une lampe à décharge de gaz améliorée ayant (i) une enveloppe de quartz cylindrique avec (ii) une fenêtre en fluorure de magnésium en forme de disque plat circulaire essentiellement transparante à la lumière à courte longueur d'onde à une extrémité de l'enveloppe cylindrique, (iii) deux électrodes en tungstène ou molybdène, entourées chacune d'un tube capillaire et (iv) une cloison dans l'enveloppe et entre les électrodes entourées de tubes, ladite cloison définissant en combinaison avec l'enveloppe un passage autour de chacune des électrodes et de son tube enveloppant. Un trajet de décharge de gaz entre les électrodes produit des points de lumière brillants aux orifices des tubes capillaires dans une région de la lampe à proximité de la fenêtre.An improved gas discharge lamp having (i) a cylindrical quartz shell with (ii) a magnesium fluoride window in the form of a circular flat disc essentially transparent to short wavelength light at one end of the shell cylindrical, (iii) two tungsten or molybdenum electrodes, each surrounded by a capillary tube and (iv) a partition in the envelope and between the electrodes surrounded by tubes, said partition defining in combination with the envelope a passage around each of the electrodes and its enveloping tube. A gas discharge path between the electrodes produces bright spots of light at the orifices of the capillary tubes in a region of the lamp near the window.
